GAS HEATER Application filed February 16, 1921. Serial No. 445,362.

My invention relates to improvements. in gas heaters of the radiant type. According to the present preferred embodiment'of my invention, the heater is so designed that it may be` converted by interchangeable parts into various forms and designs adapting it to various uses such for instance as where it may be desired to have the heater fit within a recess in a wall, or stand out in the open room with or without a hood and with or without various ornamental features which may be substituted or eliminated as may be found preferable for the particular use for which the heater is intended.

tion of air.

partly broken away illustrating a modifica# tion of the leg structure shown in Fig. 9.

Referring now more particularly to Figs. 1, 2, 3 and 4 it will be observed that the front legs 20%20 provide support for the columns 22-22f and a base 23 may be secured upon the top of the legs 20-20 by any suitable means such as the screws and bolts 24-25.

26 indicates a depending portion of the frame having flanges such as 27 adapted to be secured to the insides of the legs 20-20 by any suitable means such as the screws 28, thus bridging the legs and columns securely as shown. The hearth frame portion 29 of the heater also extends entirely between the columns above kthe legs and is secured at the base behind ythe columns by any suitn able means such as the'screws 30 and is also provided with a depending flange at the back to which is secured the sheet metal enclosure 32 as shown in Fig. 2 at 35.

The back legs ofthe .heater are indicated by the reference characters 33-33 and these legs are preferably triangular in cross-section and have upwardly extending portions 34 through which the screw or bolt 35 pron The side extensions 36 of these legs pass into the back of the bases of the'columns 22-22 where they may be secured by screws such as 37.

38 indicates the upper casting or interior frame-work of the heater, the lateral ends of which project forwardly and are secured inside of the front columns by any suitable means such as screws 39, the back of the same being suitably secured to the sheet iron back ofthe heater by suitable means such as the vbolts 40, part of the bac-k being cut away as indicated at 41 to allow for the circula-A The main frameworlrf the heater being now secured as above stated, suitable blocks or slabs of refractory or non-combustible niaterial such as indicated by reference character 41 may now be introduced between the channels 42 42 of the upper and lower castings respectively as shown to advantage in Fig. 2 and upon the front or face of these blocks of refractory material, a suitable sui'- facing of cement or other suitable n'iaterial may be applied. v

44 ndicatesother slabs or blocks of heat radiating material which may be of clay retained between the channels 45-45 also formed in the u yer andv lower castings re spectively as shown, the blocks being preferably pitched slightly forward as shown. The so-called upper channel l5 is provided with the projections 16 shown to better advantage in Fig. 1, said projections having depending forward portionsl el', and immediately in frontof these clay blocks -l/l may be secured the grilles L18 which are preferably formed in grille or other artistic forn'iation lire clay or other suitable material. The lower end of the radiant is preferably seated in the removable channel 49 which terminates atopposite ends in enlarged portions .GO which are suitably seated in the base portion 29 as shown. The upper end of the lire clay grille structure or radiant is secured by a lire clay cap such as 5l which is recessed to receive the upper end of the radiant as indicated at 52 and which is recessed at the bach to receive the upwardly projecting lugs 53 as shown. 541 are suitable tile members adapted to lit between the bach flange F5 of the upper casting and the clay caps 51 previously described.

56 are suitable side tiles or blocks preferably cut away at the bottom to cleail the ends of the enlarged portion 50 and as an inside finish as well as a protection from heat from the radiants. 57 indicates a suitable filler or metallic strap which may be extended downwardly from the side of the top casting as shown to better advantage in Fig. 5 to keep these side tiles snugly in position.

TVith the heater now assembled, as above stated, the burners 53 may now be seated upon the frame 29 of the lower casting as shown, the `connecting tube 59 thereof coming opposite the plug 60 screwed in the inanifold 61 as shown to better adivantage in 10, 62 indicating an adjustable screw needle for regulating the flow of the through the plug 60. Also projecting inwardly from the manifold 61 is the female coupling valve 63-6-64 adapted to be connected with the gas inlet pipe 65, the same being controlled by the knurled handle 66 shown in Fig. 11.

67 vindicates the front tile frame of the vheater and is provided with cross members 66 upon which suitable tiles such as 69 may be secured, thus giving a finished appearance to the heater. 70 indicates the top closure formed like an inverted channel with for` wardly projecting end portions 71-71 having tongues which pass beneath the caps 73 upon the tops of the columns 22--22. and 74-75 indicate ornaments such as shown in Fig. 6 which may be suitably secured upon the caps 73 by screws such as 76. These ornaments may be provided with an upper portion 7 5 which may be held upon the base portion 75 by the same screw 7 6 which penetrates the cap 73 as shown in detail in Fig. T.

Instead of using ornaments such as shown in Figs. 6 and 7, a hood or canopy such as shown in Fig. 8 and indicated by the reference character 77 may be employed. In that ease another cap 78 may be mounted upon the top 73 and may be secured thereto b y any suitabe means such as the screw 79 as shown.

W here the heater is to be introduced into a'n opening in a wall such as a tire place, the additional legs such shown in Fig. 9 may be employed. These may be secured at the sides Vof the pillars or columns 22-22 as shown in Fig. 1 or may be secured at the front of the saine as shown in Fig. 10, thus giving an outward sweep and additional ornamentation as well as additional stability to the heater and adapting it more particularly for inset use as above stated. Y

Referring more particularly to Figs. 12 and 13, it will be observed that as another modification, a face pla'te such as 8O may be secured in front of the hearth or openingl and 'may be provided with a hood or canopyvl such as 61. To the back of the face plate, the heater 82 may be secured as shown, extending entirely within the hearth and leaving projecting` from the front of the face plate 80, af suitable frame such as 83 and legs Se. then this arrangement is found desirable, the screws 3G-39 from the lower and upper castings respectively of the heater as shown in Fig. 2 may be secured in the bach of the frame 8O as shown. f Y F ig. 141 shows in perspective an enlarged detail of the canopy shown in Fig. 8. In the modification shown in Fig. 15, the heater is shown provided with the single side frame or casting 85 instead of the legs, columns and sheet metal bach such as 20, 22, and 32 of Figs. 1 and 2. ln the modiication shown in Fig. 16 a cap such as 86 provided with a recess 87 'to receive the pin 8S projecting from the top of the column 22 is shown. ln

hollowvornainent is illustrated and may be used either for finishing the tops of the column or for the front legs as may be found desirable, and the base portion thereof illustrated to advantaee in FiO'. 18 shows.

93 and substituted if desired for this purpose. The leg 92 is made with a screw 93 which passes upwardly through the lugs 911--95 extending from the arm 93 and terminates in the base of the ornament 90, the box 91 being cut away at 96 to allow clearance for the lugs 94-95.

Referring again to Fig. 11, it will be observed that the coupling valve comprisesthe the modification shown in F ig. 17 a suitable y sleeve 64 threaded to receive the gas inlet pipe 65 and rotatably connected by threads or otherwise at the other end to the valve 64C which in turn screws into the manifold at 63 as shown. This connection is more conveniently accessible for connecting up by removing the tile frame 67 but the hand wheel 66 though out of the way is easily accessible for operation without removing the tile frame. The tile frame it will be observed is provided with depending' lugs such as 67 to keep it from shifting after ithas been placed in position.

Of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
